FAQs

This is a team effort. We provide the tuning expertise, but there will more than likely be some mechanical issues that will need to be addressed by you or your mechanic along the way. We suggest starting with a vehicle that is in good running condition.

The log review process is designed to get the most out of your car based on your modifications. Generally, the first review will be used to identify any mechanical issues present and to address fueling. Issues that were not noticeable at stock levels generally become apparent with increased performance. Namely boost/vac leaks, MAF issues, and fueling issues. We will provide as much information as possible on how to address anything we see in the logs. Upgraded turbos and aftermarket parts increase the odds that we’ll chase additional mechanical issues, thus the additional log reviews.

Once mechanical issues are addressed we can move on to the fun stuff and fine tuning. Ensuring that your vehicle is in excellent condition will help you get the most from your tune.

Motoza PS (performance software) requires a USB port and a Windows PC (XP, Vista, 7, 8, 8.1, 10, 11).  We also recommend a 1-3 amp battery maintainer for use while flashing software to your vehicle.

Every build is custom tuned, so the timeline can vary between cars. In general, the goal is to be dialed in within 3-7 revisions depending on the tune. On average, the entire process can be completed within a few weeks. However, this time frame is subjective, as some customers are able to actively send files and logs regularly while others can only devote a few weekend hours to the process. With the exception of big turbo tunes which are quoted based on complexity, each tune comes with a set number of log reviews to be completed within 6 (six) months of initial setup.

We can pause this six month time frame for major repairs, deployed military personnel, or for family emergencies if you let us know that you would like to pause your review clock and keep us updated of your planned date to resume tuning.

We make every effort to complete setups and log reviews within 1-3 business days of submission. However, as this is a custom service, lead time may be longer depending on your build, if that’s the case, we will let you know. We schedule setups and revisions in the order they are received.

Yes, we accept returns of unused, uninstalled merchandise within 30 days. We cannot accept returns on installed parts, but do warranty defective items. Restocking fees apply for tunes that have been created and revised and verification that the ECU has been returned to stock condition is required.

Please see the Warranty and Terms Page for complete information.

Delivery times will vary based on location and shipping method chosen. We’ll send you tracking information with your order confirmation, 3-5 days is average to most US destinations. If you require expedited shipping, please get in touch!

Orders over $650.00 USD require a signature for delivery.

Shipping is from Colorado, USA. If your order is received by noon MST Monday-Friday, it will usually ship the same day. International orders may take longer due to processing requirements.

Once your kit is purchased, we will create a user account for you, (we’ll send you a link with your order confirmation). Here, your dashboard allows you to send and receive files as well as host all your data logs and tuning files in one convenient place.
We recommend leaving email notifications enabled so you are alerted when new files are uploaded for you. This account does not opt you in to any marketing emails, you will just received file notifications

Absolutely. Furthermore, you will never be penalized if your build progresses. That’s why we’re here, after all! At Motoza, loyal customers only pay the difference between the tune they have and the tune they need up to K04 and Hybrid K04 builds. Big Turbo upgrades are quoted on a case by case basis and prices are determined based on supporting modifications.

Just making some hardware changes? No problem! Minor reworks to a tune outside the 90-day window are charged a rework fee based on their complexity.

MTC stands for Multi Tune Control. It is an added feature designed to give you on-the-go control of your tunes. Using either your android based cell phone/tablet or your laptop, you can visually select your tune wherever you are with the touch of a button. It’s that simple. Added bonus, MTC comes with Launch Control for users with a manual transmission and test pipe.

User Adjustable Launch Control and Rolling Anti-Lag are available upgrade features offered with our 1.8T and 2.7T tunes for verified track cars. A manual transmission is required. A signed affidavit, along with photos of your vehicle may be required.

We can fully control all major engine parameters and accommodate projects ranging from a Stage 1 tune through larger BT projects. We are happy to tune for aftermarket injectors, oversized MAFs, CAMS, TB’s, etc…although some of these may affect pricing depending on the tuning stage. If you have any questions, please feel free to contact us for more information about your specific build.

The kit includes an MX-USB interface, carry bag, a quick start guide, and the Motoza Performance Suite software, which reads/writes the files to your ECU, performs data logging, and acts as a diagnostic tool. Also included is the expertise of our tuners who will build your file and revise it over the course of tuning. The bulk of your tune cost is for the time and labor of your tuner.

You also get a sticker that adds +2 hp.*

*Stickers do not actually increase power.

Generally, no, unless you choose to purchase an upgrade such as Multi-Tune.

Certain hardware changes do incur additional fees during the tuning process. If your build sheet changes drastically during the tuning process, there may be a fee. If you let us know what changes you plan to make from your original build sheet, we can help you find the most economical solution.

Hardware changes that may incur an additional fee during the tuning process include but are not limited to:

  • Upgraded turbos, (for example, if you replace a K03 with another K03, there is no charge. If you replace a K03 with a K04, an upgrade to the appropriate tuning stage is required).
  • Fueling components such as injectors, changes to return fueling on returnless vehicles or, water methanol not specified on your build sheet. If you think you made a mistake on your build sheet, just let us know and we’ll discuss options.
  • MAF sensor changes
  • MAP sensor changes

If minor hardware changes are made within your revision window of 6 months while you still have log reviews available, or at the suggestion of our tuners to address a mechanical issue, there is no fee for the change.
Tuner suggestions, like a change to the turbo size, MAP sensors, or major fueling changes, in an effort to further increase performance, are generally not covered. Please contact us to see if your hardware change is covered.

Yes and no. Let’s run down the tuning stages first.

Stage 1 is for vehicles with stock fueling and stock turbos and the price assumes basic bolt-ons. Upgraded intercooler? no problem. Upgraded injectors or fuel pressure regulator? Those require a move to at least Stage 1+ or Stage 2+ depending on your platform.

Stage 1+ or Stage 2 is for vehicles with upgraded fueling and the stock turbo (except in the case of the MKI TT225 which came with larger injectors and a K04; it starts at 1+). On 1.8T and 2.7T this means upgraded injectors. On a 2.0T EA113, this means upgraded HPFP internals, (see Stage 2+ for 2.0T EA113 vehicles with larger injectors). Some other fueling upgrades or a larger than stock turbo move you to the next tuning stage in terms of price. If you want to jump to injectors larger than 550cc on your 1.8T right out of the gate we can generally accommodate that depending on the injector.

  • 1.8T & 2.7T  Injectors larger than 550cc are covered if they are purchased through us. We will also cover new, genuine EV-14 based injectors from Fuel Injector Clinic, Deatschwerks, Bosch Motorsport, or Injector Dynamics with a flow report. Want to use injectors you bought off eBay or Amazon? No. Just no. Or we can give it a shot but expect to hold up the tuning process and then send them off for testing to someone reputable; this will likely put you beyond the usual number of log reviews. We will gladly provide a list of companies who test injectors, and provide ACCRUATE, usable data and one to avoid. Most of the bigger names in aftermarket Euro parts sell quality injectors. When in doubt, contact us first. OEM Bosch 386cc injectors or Bosch 440 Green Giants can be used on 1+ cars with gasoline or WMI, (they are not sufficient for E85 use). We will work with with Siemens 630cc, but they incur an additional charge and are not the ideal choice. Upgraded fuel pumps, return fuel conversions, and upgraded FPRs are included.
  • 2.0T When it comes to HPFP internals, we will work with most of them assuming they came from a reputable source. And yes, that even includes some other tuning companies. Again, Amazon and eBay are not reputable sources for most parts.

Hybrid K04 – Stock Block This is for any turbo with a K04 sized compressor housing, including BorgWarner K04s. If you have a TT225, this covers FrankenTurbo, TTE, or any K04 sized turbo with larger than stock internals that is not a direct OEM replacement. The same injector rules above apply. Standard bolt-ons like intercoolers, exhausts, 3″ MAF housing with the OEM sensor, complete TT225 MAFs, or complete VR6 MAFs. We just really need to know your exact MAF setup. Rods, cams, head swaps, other MAF setups and 3bar MAP sensors move you to one of the categories below.

Hybrid K04 – Built Block If you’ve upgraded rods, installed mild aftermarket cams, gone to an AEB head or otherwise modified the block, this covers any K04 sized turbo with those mods. It also covers 3bar MAP sensors.

Hybrid K04 – Built Block+ This is where you land if you’ve done block mods and 3bar MAP sensor with the addition of aggressive cams or have a blow-through or MAFless setup. Probably a good idea to email us at this point.

Big Turbo – This is for any turbo larger than a K04. A built bottom end is a really stellar idea. Anything larger than a GTRS will REQUIRE a built bottom end in most cases. Pricing is by quote. If you submit a quote request wanting to hit 500 wheel horsepower on a stock block 1.8T, we will likely assume you are trolling. If you would like to send us an email and discuss what it takes to meet your power goals on any of the platforms we support, we are more than happy to help. If you have big power goals and need to complete your build in phases due to budget, we can tune in phases. Just talk to us.

Ok, this brings us to the more difficult part of the conversation. There are definitely things that CAN be done, but whether they SHOULD be done or if the stock ECU, stock block, stock fuel system, etc. is a good place to do them, is an entirely different matter. Then there are things that can be done but cost more.

Using a screen door spring to fix a soft wastegate is technically possible for a short period of time. It’s not a great idea. We definitely won’t tune for it. Really want to go MAFless on a Stage 1 so you can run a loud BOV, sure, but

Our Stage 1+ tunes are intended for turbos that were stock to the vehicle. In the case of the Audi TT, for example, we skip Stage 1 and go directly to 1+ since the stock turbo was a K04.

If you’ve upgraded your turbo from the stock K03 to an OEM K04 turbo, the Hybrid K04 tune encompasses OEM K04s installed on vehicles that came stock with a K03, or bundle options are available.

Typically, tunes are completed with the following number of log reviews:

Stage 1: 1-3

Stage 1+: 1-4

Hybrid K04: 5-7

Big Turbo: 5-9

A log review will not always result in a revision/new file. If there is a mechanical issue that needs to be addressed, we will let you know and may suggest that you take your vehicle to an experienced mechanic. The suggestion to see a mechanic does not mean that we think you’re not awesome; it means that sometimes people who do highly specialized work every day will ultimately save you time and money, have the proper tools, and give you a better shot at success. You probably don’t want your family doctor performing your heart transplant. Doesn’t mean they’re not a fine physician, just that some things need specialists. Engine building and electrics fall into this category.

Absolutely! They can be used if you need to do additional troubleshooting or if a few years go by and your car develops an issue that you’d like help diagnosing. Additional reviews can be purchased for $50.00 for a single review or minor hardware change, $99.00 for a three pack or minor hardware change + 2 log reivews, or a 3 pack for $120 that can be used within 90 days. Just email us if you need more.

When VAG moved to chain drives, they also switched ECU suppliers for the 2.0T platform. If you have questions about which engine you have, please feel free to contact support with your engine code and we can confirm compatibility.

The MX-USB interface, as well as the Motoza PS software, are yours to keep.
